Rooster?

[Burnttoast5475]

My blue laced red Wyandottes got so big but I think the more blue one might be a rooster. I know this breed have big waddles but I think it’s a boy

How old are they? If it is the same age as the GLW, it's likely it is male. Might need a full-body side picture or one from the top that shows the feathers clearly to make a better guess.
